Abstract: The assessment of ecological resilience holds significant theoretical importance for the high-quality development of the Yangtze River Economic Belt (YREB). This study constructs an ecological resilience evaluation system based on the Pressure-State-Response (PSR) model by selecting pressure, state, and response indicators. It investigates the spatiotemporal evolution of ecological resilience in the YREB from 2008 to 2018, regional disparities, and their underlying causes. The results indicate that: (1) The overall ecological resilience of the YREB exhibited a fluctuating upward trend during 2008-2018. (2) Distinct regional drivers were identified: ecological resilience in the upstream regions correlated strongly with response indicators, midstream regions showed closer ties to pressure indicators, and downstream regions demonstrated interdependencies between resilience and both state and response indicators. Specifically, fluctuations in the response index reflect the intensity of investment, variations in the pressure index indicate the pace of urbanization processes, and changes in the state index correspond to the dynamics of water resource conditions. This research provides a scientific foundation for ecological conservation and sustainable development in the YREB, elucidates the impact of human activities on ecological environments, and offers strategic insights for achieving high-quality development under the "Yangtze River Protection" framework.
